How were the planets in our solar system discovered? Only two of our eight planets have real discoverers and time of discovery. They are Uranus and Neptune. Pluto was considered a planet once but isn't anymore.

Discovery of Uranus: Uranus was discovered by Sir William Herschel in 1781. He was the most famous astronomer in the 18th century, Including the discovery of Uranus, he also found and reported over 800 double stars and 2,500 nebulae.

Discovery of Neptune: Neptune was discovered by John Couch Adams in 1846. Adams was a english astronomer and mathematician. Adams did not report his prediction and its amazing that he got credit by the scientific community for his work. Astronomer Johann Gottfried Galle (along with Heinrich Louis d'Arrest) established the existence of Neptune based on independent, published calculations by, mathematician Urbain Jean Joseph Le Verrier.
Discovery of Pluto: Pluto was discovered by Clyde Tombaugh in 1930. Pluto was once considered a planet but is not anymore because Pluto does not fit the requirements to be a planet. The word planet did not have an official definition. The definition of planet is, "A full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit." Pluto isn't a planet because it does not dominate its neighbourhood and Charon, its moon is about half the size of pluto, while the other planets are much greater than there moons. How do scientists find planets outside our solar system?The Wobble method: Scientists use the wobble method. The wobble method is used for finding planets. Astronomers look for stars that wobble, Some stars wobble because it has a planet around them. Stars and planets orbit each other, so the planets pull makes the star move a bit and scientists look for wobbling stars. Uranus
